Study Notes

Respiratory Disorders Lecture Notes

  • Respiratory disease affects 1 in 5 people.
  • It is the 3rd largest cause of death in England.
  • 25% of patients may have a respiratory disorder.
  • Lung cancer, COPD, and pneumonia are significant causes of death (NHS England).
  • Smoking is a major risk factor, especially in lower socioeconomic groups.
  • Dental professionals need to understand how respiratory disorders impact oral health.

Aims & Learning Objectives

  • Explain the different components of the respiratory system.
  • Explain pulmonary ventilation and perfusion.
  • Define respiratory disorders.
  • Identify different types of lung diseases.
  • Describe the pathophysiology of common respiratory disorders (e.g., asthma).
  • Describe how to manage a respiratory emergency.
  • Explain how dental treatments could be affected by respiratory conditions.
  • Describe medications used by patients with respiratory illnesses and their relevance to dentistry.

Structure of the Lecture

  • Part 1: Review of respiratory system anatomy and physiology (ventilation and perfusion).
  • Part 2: Understanding the occurrence of respiratory diseases, including classifications, common lung conditions, signs, symptoms, and treatments.
  • Part 3: In-depth look at asthma and COPD, including pathophysiology, signs/symptoms, and treatments.
  • Part 4: Managing dental patients with respiratory diseases, including patient management, clinical considerations, smoking cessation/prevention, medical emergencies, and group discussion.

Respiratory System Anatomy and Physiology

  • The respiratory system consists of airways, lungs, muscles of respiration, and blood vessels.
  • Air is breathed in and out via the airways (nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli).
  • The lungs are responsible for gas exchange.
  • Muscles (diaphragm and intercostal) facilitate breathing.
  • Pulmonary circulation moves blood to and from the lungs for gas exchange, with arteries carrying blood to the lungs and veins carrying it back to the heart.

Common Lung Diseases

  • Asthma: A chronic inflammatory disorder of the airways.
  • COPD: A progressive lung disease caused by smoking (including chronic bronchitis and emphysema).
  • Lung Cancer: One of the most common and serious types of cancer, often linked to smoking.
  • Pneumonia: Inflammation of the lungs, often caused by bacterial or viral infection.
  • Pleural Effusion: Fluid buildup around the lungs, impacting their ability to expand.

Asthma: Key Points

  • Asthma affects people of all ages.
  • 12% of the UK population has asthma, and 4% have severe asthma.
  • Triggers (e.g., allergens, stress, cold air) cause inflammation and narrowing of airways, leading to symptoms like wheezing, coughing, and shortness of breath.
  • Asthma attacks are acute exacerbations of the condition.

COPD: Key Points

  • COPD encompasses chronic bronchitis and emphysema, impacting the ability to breathe effectively.
  • The disease progresses and is often irreversible.
  • Smoking is the primary risk factor.
  • COPD is a significant cause of death in adults.

Bronchitis:

  • Inflammation and narrowing of the airways, often associated with mucus production.

Emphysema:

  • Damage and breakdown of the alveoli (air sacs) in the lungs, reducing gas exchange.

Asthma Management

  • Medications aim to prevent or relieve asthma symptoms (narrowing, edema, inflammation).
  • Medications are prescribed based on factors like patient's age, symptoms, severity of asthma, and other medical conditions.

COPD Management

  • Prevention (stop smoking) is key.
  • Vaccinations (like the flu).
  • Exercise programs.
  • Tailored management plan considering overall health and comorbidities.
  • Medications to improve breathlessness and prevent exacerbations.
  • In severe cases, supplemental oxygen therapy may be required.

Dental Management Asthma

  • Detailed patient history (diagnosis date/duration, medication use/frequency, hospitalizations, triggers, allergies/allergies).
  • Social history including smoking status.
  • Identifying triggers in the dental practice.
  • Understanding the severity and risk factors.
  • Appropriate materials for dental procedures

Dental Management COPD

  • Comprehensive patient history (medications, triggers, severity, oxygen use, hospitalizations).
  • Smoking cessation advice/documentation.
  • Monitoring patient's oxygen saturation (SATS) levels before, during, and after procedures.
  • Consider needing oxygen therapy if low levels.
  • Consult senior personnel for necessary assistance.

Medical Emergencies

  • Patients can collapse at any time.
  • Dental professionals need training in and evidence for dealing with medical emergencies like resuscitation.
  • Risk management in the dental setting.
  • Take a complete patient history, conduct thorough assessments before procedures, and ensure the presence of two trained medical professionals.
  • Know how to manage medical emergencies (CPR, recognizing signs of respiratory distress, asthma attacks, anaphylaxis).

Anaphylaxis

  • Symptoms include sudden onset, flushing, respiratory distress, hypotension, rapid symptom progression, and life-threatening changes to skin/mucosal membranes.
  • Management involves implementing ABCDE methodology, calling emergency services, positioning the patient (flat/elevated legs if breathing unaffected), administering oxygen (15L/min), and giving intravenous adrenaline immediately.
